STOCK-TANK HEATER.

Application filed June 25, 1924. Serial No. 722,378.

T all cli/10m it may concern.'

Be it known that I, EDWARD F. Crow, a citizen of the United States,residing at Pleasantridge, in the county of Perkins and State of SouthDakota, have invented new and useful Improvements in Stock-Tank Heaters,of which the following is a specification.

This invention relates to stock tank heat- `ers of the submergible type,wherein the heater is adapted to be placed within the tank with the`major portion arranged beneath the level of the water, and used tomaintain the water at a temperature to prevent freezing. e,

,One of the chief characteristics of the present invention resides inthe use of one or more water coils wholly disposed within the heaterdirectly above the gratethereof, with the terminals of the coil openingat the sides ofthe casing to allow the water within the tank to passthrough said coils, whereby 'the water is quickly heated for the purposeabove mentioned.

Another important object of the in-` vention resides in the provision ofa heater equipped with air draft tubes, one of which is centrallydisposed and susceptible of vertical adjustment, means being providedfor supportinof the adjustabledraft tube in any y given position, thetube being provided with a damper lof any well known construction.

y therefrom, and supported in its elevated- In carrying out ytheinvention l also provide va supporting structure for the heater per se,the heater being suspended from an overhead support and capable of beingconveniently lowered intothe tank or raised position when not in use.

- The `nat-ureand advantages of the invention will be. better understoodwhen the following detailed description is read in connection with thelaccompanying drawings7 the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals ofreference indicate similar parts in the several views, and wherein:

Figure 1 is a view in elevation of the heater, certain of the partsbeing illustrated in section,

Figure 2 is a view taken on a right angle to Figure 1,

Figure 3 is a top plan view of the heater, showing` the smoke stack insection,

Figure lis a transverse sectional view through the heater,

Figure 5 is a plan view of the base of the supporting structure.

Referring to the drawings in detail represents a stationary base andforms part of the supporting structure for the heater per se. This baseis preferably7 of rectangle lar contour in plan as clearly shown inFigu-re 5., while rising from two opposed sides of the base are parallelstandards 11. The base 1() is further connected with these standards bymeans of wire brace elements, each including intermediate coil 12receiving the Aadjacent standard l1,

and divergently disposed limbs 13 hav-` ing their extremities offset asat 14 to be received by openings formed in the adjacent side of the base10. This structure is also shown in Figure 5. rThe standards 11 areconnected at a point adjacent their upper ends by a transverse member l5which has a central opening therein, and rising from this transversemember about the edge of said opening is a hollow tubular member theheater per se, while the other eXtremities of the cables are connectedto similar lugs 23 through the instrumentality of coil springs 24. Thesesprings 24 being arranged in the length of the cable serve to maintainthe latter taut. It will be noted upon inspection of Figure 3 that theapertured lugs 22 and 23 receive the standards 11, and are adapted toslide upon said standards when the heater per se is either lowered intothe stock tank, not shown, or raised to an elevated position whollyabove the tank. The heater per se includes a casing 25 preferably ofrectangular contour in cross section, which casing is equipped with acover 26. This casing of course defines or provides a lire chamber inwhich is arranged the heater.

a grate 27 of any desired construction. Depending from the top 2G aboutthe marginal edge thereof is a plurality of down draft tubes 28, which:have their upper ends extending above the cover,` and their lower endsextended inwardly beneath the grate as indicated at 29. Each draft tube28 is sup ported by apertured lugs 30 projecting inwardly from theadjacent walls of thecasing 25. The grate 27 `is formed with lugs 27which embrace the adjacent draft tubes 28, to which they are secured toassist in supporting the grate in a manner illustrated. The grate isfurther supported by webs or lugs 29 rising from the inwardly extendedportions 29 of the draft tubes 28 as shown in Figure 1. In addition tothe draft tube 28 ,I also employ a central draft tube 31 which isvertically adjustable through an opening formed in the top or cover 26of This central draft tube is equipped with a damper 32 at a pointadjacent its upper end. rIhe draft tube 31 is also arranged immediatelyadjacent and parallel with the smoke stack 33, the lat-V ter Vbeingprovided with a verticalr series vof staples or the like 34 utilized tosupport the adjustable draft tube 31 in any given position. This tube 31is formed with a hook 35 arranged tol engage any one of the staples 34supported by the smoke stack Arranged within the casing 25 is one ormore coils as clearly shown in Figures 1 and 2, the coils being arrangedabout ythe central draft tube 31, and have their extremities openinginto the stock tank, which extremities pass through openings formed inthe adjacent sides of the casing 25. The corresponding lower extremities36 of thev coils herein illustrated constitute the `inlet ends of saidcoils, While the upper extremities Vd? constitute the outlet coils. Thenthe heater 1s submerged into the water contained in the stock tank, thewater 'therein enters the coils through the inlet ends 3G thereof, andafter `circulating within said coils returns to thev tank through theoutlet ends 37 of said coils. By reason of the fact that the coils arearranged immediately above the grate 27, the

coils are subjected to the maximum heat of", the firev adapted Ato bemadewithin the .grate` Y 27, and consequently the water Within the stocktank can be quickly heated from time to time with a view of maintainingthe tem! Vsmoke stack 33' passes throughthe tubular member 16hereinabove referred to, While the hooks 38 rising from the cover 26 ofthe heater is adapted to engage the cross member 15, to suspendtheheate'r' from said cross Amember or in other words support the heaterin an elevated position.

While itvis believed that from the foregoing description, the nature andadvantages of the invention will be readily apparent, I desire to haveit understood that -I donot limit myself to what is herein shown anddescribed, and that such changesmay be Y rresorted to when desired asfall Within the scope of what is claimed. I claim: A stock tank heatercomprising acasing,

a closure therefor having openings there` in, a grating arranged Withinthe casing and spaced from the walls thereof, means for supporting thegrate, downdraft tubes depending from. said closure and havin theirupper ends projected through sai openings, the corresponding lower endsof said tubes being directed inwardly and ar` ranged immediately beneath`the grate, eye

members holding said tubes associated with the casing, a draft tube deending centrally" from said closure and having its upper en d projectingabove the closure, said casing'having spaced openings atthe oppositesides thereof, water heating coils surrounding the last mentioned tubeand arranged Within the casing, the free ends of each coil projectingthrough the adjacent openings in one side of the casing, and a smokestack risingfrom the casing.

jIn testimony whereof I alix my si nature." EDWARD F. C
